1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesTo compare the survival and success rates of autotransplanted immature teeth versus mature teeth treated with extraoral root-end resection (EORER), and assess inter-rater agreement in radiographic evaluation between oral surgeons (OS) and general practitioners (GPs). MATERIALS AND

methodsPatients who underwent autotransplantation between 2000 and 2022 were retrospectively identified and invited for clinical and radiographic follow-up examinations. Periapical radiographs were independently evaluated by three OS and three GPs. Predictors of survival and success were analyzed using univariate generalized estimating equation models.

resultsFifty-eight autotransplanted teeth (39 immature, 19 mature) in 50 patients were included. Immature transplants showed higher survival (89.7% vs. 73.7%; mean follow-up 8.4 vs. 5.6 years) and higher success rates (63.3% vs. 31.3%) than EORER-treated mature transplants. Pulp revascularization was observed in 88.5% of immature and 54.5% of EORER-treated mature teeth. Longer splinting and pristine recipient sites were associated with higher survival; premolar and molar sites with higher success (p ≤ 0.047). Inter-rater agreement was lowest for pulp canal obliteration, with OS showing higher agreement than GPs (p = 0.02). GPs generally reported more pathological findings on the radiographs.

conclusionsImmature transplants demonstrated higher survival and success rates than EORER-treated mature transplants. However, pulp revascularization was observed in over half of mature transplants. Radiographic assessment varied considerably between OS and GPs. CLINICAL RELEVANCE: Immature donor teeth remain the preferred option for autotransplantation. Nevertheless, EORER extends eligibility to mature donor teeth by promoting pulp revascularization, potentially avoiding root canal treatment. Standardized radiographic criteria and calibration are warranted for follow-up over time.
